Altervolt develops high isolation voltage power supply designed for the needs of multilevel power converter used on medium voltage network. Multilevel power converter needs to supply every modules or semiconductor of each level with an auxiliary power supply which has to sustain the overall isolation voltage.
The parasitic capacitor has to be as small as possible to limit the parasitic current during the switching time between two levels of the converters. Our design reduces parasitic capacitance to values as low as 6 pF.

Many other applications need a high isolation voltage and a small parasitic capacitor. For all these products, our power supply can provide a solution.

Easy to use

Our goal is to provide easy to use power supplies. All the necessary protections are inside, the overall isolation let you place the power supply one next to the other., this allows the realisation of a converter in 19″ racks.

The key points are

  • Wide input voltage range from 12V to 30V
  • Shorted circuit output protected
  • Three common used output voltage
  • Reinforced isolation
  • very small parasitic capacitance

Standards for certification

The certification of all our power supplies are following the best standards used in power electronic domain.

  • IEC 62477-2 : Safety requirements for power electronic converter systems and equipment – Part 2: Power electronic converters from 1 000 V AC or 1 500 V DC up to 36 kV AC or 54 kV DC
  • IEC 62103 : Electronic equipment for use in power installations
  • EN 61800-5 ; Adjustable speed electrical power drive systems – Part 5-1 : safety requirements – Electrical, thermal and energy
